I bought the small humidifier to keep by my bed, planning to run it at night. The first night it worked like it was supposed to. When the water ran out, it stopped as it was supposed to. I added more water and turned it back on the next evening, and it would not work. I followed the manual as to what to do in the event that the unit would not start. It still would not work. Over all, I got one use out of it. I am very disappointed in this product and would not recommend it to anyone. Even though it did not cost very much, it was a waste of my money.

So, to conclude, I didn't find anything great about it, and one big thing not so great.
